To all whom it may concern:

lle it known that` l. JOHN Osuna, 'a

citizen 'ot the. 4llnited States. residing at Chicago. in the eonntv of Cook and State of Illinois, have invented certain new and iet-ful improvements in \\'aterl.ift. ot

which the following is a s}weiteation.

This invention relates to apparatus forl forcing water b v means of liuid pressure,

vaud is cspevialluapplicable to apparatus:

intended to be suhmergedin a body of water tor torcmg the water to an elevated tank or distributing system.

'lhe object of this invention is to simplify and improvethe construction of apparatus ol' this class.

. ln the accompanying drawings, Figure 1 is a vertical central section through an appiiratns embodying the. features of iny invention. Fig. 2 is atop plan view thereof. Fig. El is a section on line 3 3 of Fig. 1. Figs. 4 and 5 are sections on linesfi 4 and 5 respectively, of Fig. 1. Fig. 6 is an underside view of an oscillatory valve member employed in the construction. Fig. 7

is a section on line 7 7of Fig. 6. Figs. 8 and 9 are sections on lines 8 8 and 9 9, re-

.spel-tively, of Fig. 2. Figs. and 1l are sections on lines` ttl 'l0 and 1l ll. respectively, of Fig. l. i

'lhe embodiment. herein shown of my invention comprises a casing 1 of any suitable form, said casing having an upper head 2 and a lower head 3. The casing 1 is intended to be submerged in a well or other body of water. Vater is admitted to the interior of the casing 1 through an inlet opening 4 i 'ffii-med in a small chamber 5 uponv the under side ot' the lower head 3. Said opening is arranged to be closed by a gravity valve i 'lhe chamber 5 communicates with the interior of the casing 1 through an opening 7. l i

Tater is forced from the casing 1 to an elevated tank or distributing system (notshown) through a'pipe 8 attached, in this I The lower-'i 'ins-tance. to' the upper head 2.

Y end of the pipe 8 extends to apoint adjacent.

to the bottom of the casing 1 and is there provided with a closing cap 9 having an opening 10 therein, said opening being arranged to be closed by a. eleek valve. 11 of any suitable construction. 1 haveherein `hoxvn a valve member adapted to seat upon the conical valve seat 12 and having a flnted -|em 13 (Fig. 11) which is slidable in the pcning 10 of the closing cap 9. Pressure E within the casing 1 in excess of pressure in the pipe 8 will unseat the valve 11 to permit g the entrance of water to said pipe, the un-4 seating movement of the valve being limited 'oy suitable means, such as a pin or collar 14.

water from the casing 1 into and through the pipe 8 ma)r be compressed air or steam. t The means for controlling the tiow of the pressure fluid comprises, in this instance, a y valve chest 15 comnmnicating with a suitable supply of pressure fluid through a. pipe 1G. In this instance the lower side of the K valve chest 15 is integral with the upper casi ing head 2. Upon a. valve face 17 in said pressure chest. is positioned an oscillatory i valve member 18, which member is rigidly mounted upon the upper end of a valve spindle 19 extending through the lower Wall of the valve chest 15 and the casing head 2 into the interior of the casing 1. herein shown two ports 20 and 21 extending between the valve face 1'Z and the interior of the casing 17 the valve member being provided with two ports 22 and 23 adapted to register with the posts 20 and 21, respectively.- In the valve face 17 is a port 21 the pressure (luid. ln the -lower side of the. valve. member 1S is formed a. groove. or `re cess iti adapted to connect the port. 21 with the port, 2l in order to atford an outletfor the pressure fluid in the casing 1.

The valve member 18 is arranged to be oscillated to place the interior of the casing 1 alternately in communication with the inp terior of the valve chest 15 and the outletpipe 25.- The means herein. shown for thus moving the valve member 18 comprises a float 2 carried by an arm 28 which is pivotallv supported at one end upon lugs 29 upon the side wall of the casing 1 near its upper end. Upon the tloat arm 28 is a projection 30 which is connected by means of a lilik 31 with an arm 32 fixed to the lower 'end of the valve spindle 19. lt. will be seen that as the tloat 2T is moved up and down, the valve member 1S will be oscillated to connect the interior of the casing 1 with the pressure supply pipe 16 or the exhaust pipe 25. The movements of the float arm 28 are 5 limited by sto pins 33.

In order to old the float- 2'( elevated after it has actuated the valve member 18 to c011- nect the interior of the casing 1 with the l pressure supply pipe so that the water -level I have The pressure fluid employed to force roo Q -p kn l '981,301

in the casing may be lowered without imme-V diately lowering the float, I provide a de- .tent 34 having teeth thereon which are arranged to be engaged by a tooth 35 on the float. The detent 34 is pivotally supported at 36 upon the side wall of the casing l. A. weighted arm 37 fixed to the detent tends to tilt said detent into position to engage the tooth 38 is a stop pin for limiting the pivotal movement of the detent 34 in one direction. l

To operate the detent 34 to release the float 27 when the water level in the casing 1 has been reduced to a desired point, I provide a float 39 fixed upon an arm 40 which is pivoted at one end upon lugs 41 upon the side wall of the casing 1 near the lower end thereof. The lugs 41 are, in this instance, positioned upon the opposite side of the casing from the lugs 29 which support the upper iloat arm 28.' Stop pins442 limit the pivotal movement of the lower ioat arm 40. A vrod 43 connected at its lower end t0 the float arm 40 extends loosely through an arm 44 fixed to the detent 34 and has at its upper end a head or other projection 45. It will be seen that when the lower loat 39 de-V scends, the head 45 -will engage the arm 44 and tilt the detent away from the lloat 27, thereby permitting said float to descend and operate the valve 18 to place the casing in communication with the outlet pipe-25. It will be seen that the oat 39 will operate the detent- 34 and thas cause an operation of the valve member 18 before the water level in l the casino 1 has fallen below the level of the lower end of the outlet pipe 8.

To assist the lipat 27 and the arm 28 in voperating the valve 18 to ciose communication between the pressure supply pipe and the interior of the casing l, I provide a eonnection between the Vfloat. arm 28 and the float arm 40. Said connection may be of any suitable chararter. I have herein shown a wire 46 having a loop 47 upon its upper end, `which loop passes through a wire loop 48 connected to the tloat arm 28. Pins 4.)

lshown in Fig. 1, with the valve member 18 in the. position indicated in Fig. 9 and the upper part of the casing l to be filled with pressure fluid, the operation is as fullo- The fluid preis-ure the upper pari t uw casing 1 will cause the water in sain .sirtolbe forced through the opening im. and through the outlet pi 8. The i.: e sur.4

y preurelairv valve 6 seated. As soon as the. level of the water has fallen to about the level indicated by the dotted line a. in Fig. 1, the float 39 will begin to descend. As said float descends, the head upon the rod 43 operates io diseugage the dctent from the float 27,

which thereupon Vfalls .to the position indi-A upon tlie water outside the casing 1 opens the valve member 6 and enters the casing 1. When the level of the water in the easing 1 has risen tosuch a height as to rais(` the float 27 into the position shown in Fig. l, the valve member 18 will have turned into the position indicated in Fig. 9, thereby permitting the entrance of pressure liuid to the casingl and causing the discharge of water from said casing into and through the pipe S..
